Brentford have launched a bid for Real Betis attacker Assane Diao.

The Spain U21 international has enjoyed a breakout year in 2023 with Manuel Pellegrini's Betis.

Revelo says Brentford have shown interest in Diao, who has a contract with Real Betis until the summer of 2027.

They have made a bid of almost €30m for the 18-year-old.

Diao's buyout clause is set at the same price, but Real Betis at the same time want to extend Diao's deal.

The offer would include upping his buyout clause to €50m.
